Limestone and Acid Rain

The presence of limestone and other calcium carbonate rock in lakes and streams helps to maintain a constant pH because the minerals react with the excess acid However acid rain eventually can overcome the buffering capacity of the surface water Back Compass Index Tables Introduction Next

The Limestone Chemistry Cycle

The reaction carries on as long as the tube is heated Continue to heat until all of the limestone has decomposed The solid left is calcium oxide known also as quicklime The final mass of the quick lime is about 5 6 g but you started with 10 g Where has the 4 4 g gone? If you heated 1000 tonnes of limestone how much quick lime would you get?
